However, the 36-year-old might want to take a leaf out of her sister-in-law-to-be's book and create a homemade gift for the Queen.

Last Christmas, the Duchess revealed she was worried about what to buy her grandmother-in-law.

"I thought 'I'll make her something,'" she admitted, reports the BBC, "which could have gone horribly wrong."

Instead the mother-of-two opted to make the queen her grandmother's recipe of chutney.

"I was slightly worried about it, but I noticed the next day that it was on the table," she added.

In true royal fashion, the festivities will get underway on Christmas Eve in the White Drawing Room at Sandringham to exchange presents and finish decorating their 20ft tree.

Afterwards, Markle and her new family will enjoy a typically British tea of scones, sandwiches and cakes before retiring to dress for a formal dinner.

In the morning, each royal is known to wake to a small stocking of small gifts and fruit at the end of their beds.

Royal historian Kate Williams told the BBC: "It's quite set, it's quite formal. It's looked pretty much the same since the Queen's youth, since the 50s.

"You arrive when told to arrive... There are quite a lot of different dresses required—change for church, change for dinner."

Following a service at St. Mary Magdalene Church in the local village, the family will greet well-wishers before returning to the estate for a traditional turkey lunch.

However, the actress, who is accustomed to Christmas dinners in Toronto and California, might find some of the royal traditions somewhat bizarre as, after lunch, she will reportedly be separated from her fiancé with the other ladies when the Queen signals for the corgis to be led out.

Meanwhile, the Duke of Edinburgh will serve port and brandy to the men.
